PAPER-CUTTING MACHINE.

FQPECIFICATION forming part of Letters Patent N0. 767,676, dated August 16, 1904.

Application filed May 1, 1903. Serial No. 155,122. (No model.)

To all whom it may concern:

Be it known that I, LAURA ALLIss, a citizen of the Dominion of Canada, residing at Sandwich, in the county of Essex, Province of Ontario, Canada, have invented certain new and useful Improvements in Paper-Cutting Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a machine for trimming and cutting wall-paper; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object of the invention is to provide simple and efficient means for trimming or cutting a roll of paper, the arrangement being such as to enable the paper to be trimmed or cut at any desired point and to be wound from one roll onto another during the operation of cutting.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a machine embodying my invention. Fig. 2 is a transverse section as on line 2 2 of Fig. 1. Fig. 3 is an enlarged detail in perspective of one of the boxes in which is journaled the cuttercarrying shaft. Fig. 4 is a perspective View of the guide-plates between which the paper passes from the roll. Fig. 5 is an enlarged detail of the cutter and of the beveled channels in the bed in which said cutter rotates. Fig. 6 is an enlarged detail in section showing the manner of adjusting the guide-plate. Fig. 7 is a perspective view of a split shaft adapted to receive the paper as it passes from the cutter and to wind it thereon.

Referring to the characters of reference, 1 designates a suitable frame upon which the mechanism is mounted. Extending longitudinally of the frame between the ends thereof is a bed2 in which is formed transversely thereof a series of beveled channels 3. J ournaled at its opposite ends in hinged boxes 4, mounted upon the frame of the machine, is a shaft 5, carrying at one end a gear 6 and a crank 7. This shaft is square between the points, which have bearing in the boxes, and mounted to slide upon said shaft is a cutterdisk 8. This disk is adapted to engage in any one of the V-shaped channels in the bed, with which it may be made to register by moving it longitudinally upon the shaft.

The paper to be cut or trimmed is in the form of a roll 9 and is mounted upon the shaft 10, which is passed therethrough and which is removably seated in the boxes 11. Also removably seated in the boxes 12 at the opposite side of the machine is a split shaft 13, adapted to receive the paper between the halves thereof and to be clamped together by a screw 14, whereby the paper is securely held and may be wound upon said shaft by rotation thereof. This rotation of said shaft is accomplished through the medium of the gear-wheel 15, which meshes with the gear 6, which is driven by the turning of the crank 7.

r j Below the roll 9 of paper are the curved guide-plates 16, between which the paper passes from said roll and from which it leads to the bed 2, across which it is drawn under the rotary knife or cutter 8, and from which it passes to and is wound from shaft 13. The rotation of the gear-wheel 6 by means of the crank imparts movement to the shaft 13, so that the roll of paper is wound thereon simultaneously with the rotation of the knife 8, whereby as the paper is drawn across the table said knife cuts it so as to trim the marginal edge therefrom or to sever the paper at any other point, accordingly as said knife may be dadjusted to any one of the channels in the be A guide-plate 17 is adjustably secured in the bed by means of a threaded stem 18 thereon, which passes through a slot 19 in the bed and receives a thumb-screw 20. This plate 17 forms a guide against which the paper runs and which directs it in a straight line across the bed.

The possible adjustment of the cutting-knife is illustrated by dotted lines in Fig. 1, where said knife is shown as cutting near the center of the roll of paper where it is desired to split the roll for filling in a narrow strip of wall or for other purposes. To adjust said cuttingknife, the shaft 5 is raised from its hinged boxes 4: and the knife moved longitudinally thereon to the desired position. The proximity of the V-shaped channels 3 in the bed and adjustment of the guide-plate 17 enables the machine to be so set as to cut the paper at any desired point. The rotation of the shaft 13 winds the paper thereon and draws it across the table from the roll 9, which rotates to allow the paper to unwind therefrom as it is drawn into the machine.

Having thus fully set forth my invention,

and means for driving the cutter-shaft simultaneously with the movement of the paper across the bed.

2. In a machine for the purpose set forth, the combination of a frame,a shaft journaled at the rear of the frame, having means for clamping a roll of paper thereto, a cutter-shaft journaled in front of said first mentioned shaft and mounted to move vertically, a bed below the LAURA ALLISS.
